Who in Australia could upgrade the 7sp Automatic gearbox to handle more TQ output? I already have a billet flex plate and plan on getting the line pressure adjusted via tune. Is there anything else one could do to strengthen it?

Got another email from DPTI saying I can be approved for adding a turbocharger system to a NA engine, even though my engine was never produced from factory with a turbocharger before. Going to call Martin tommorow to get his opinion.

Oh shit this is f**ked!! My build is too extreme to be able to restock it then rebuild it every time. I have way too many parts invested into this, would cost me shit loads!! Not sure what to do now? I have already bought all the parts and I don't really want to drive around without a roadworthy certificate and then get busted. But I got an e-mail back from DPTI who are saying I am able to do the turbo conversion provided it goes through the correct procedures and correct testing. And they also stated their is 2 emission testing facilities in SA, Bells Auto and Graham West Workshop. They just said I have to submit the application for modification and they will give me the statement of requirements.

It costs 10s of thousands to have a car engineered?? Wtf, I did not know this. If it were a few $K I would be ok with it but if you are really being honest its over $10K then yes I would be pretty f**ked. You are rite I have never dealt with regency and SAPOL about car modifications before. I have no idea in this field that's why I came here. I thought Regency are the ones who approve and give you the paper work or certificate to say it is legal and roadworthy to register and drive the car? So why do SAPOL send you back to the ones who issue the certificate, wouldnt that just be sending you in circles. And if they did suspect you modified the car more after the certificate and you proved to them you didnt by taking it to regency, can't you sue them or get the money back for making you goto Regency again for no reason? Surely they couldn't just continue to make you goto Regency and pay all the fees just because they suspect something?

Hey mate I don't kow how correct you are about not being able to add a turbo charger to an N/A car and not being aloud to tune the ECU at all. I was just reading the SA aftermarket modification webpage: https://www.sa.gov.au/topics/driving-and-transport/vehicles/vehicle-standards-and-modifications/aftermarket-components And it seems in both cases I can add the Turbo kit or ECU tune, aslong as I can pass the emission testing. I am going to call DPTI and Martin later to confirm this. And about the getting the GTR for $100K, I did consider this approach but even if I sold my Z and all the parts I have for my TT build, I would be lucky to get $70K. I would still be short $30K for a GTR. So that option is definitly a no go for me.

Anyone give me opinions/info/insight into legally modifying cars in SA. I just want to know how lenient or strict they are in passing cars that are modified in SA. I have a stock Nissan 370Z, just been lowered and have aftermarket wheels on. I have the plan on doing a Twin Turbo conversion with many smaller/supporting mods.

They will issue me statement of requirements and possibly require an engineers report. Then I am to book in for a roadworthy testing and possibly emissions testing. I already have all the parts above except the Exhaust system, just waiting on that before I go ahead with the build. Planning on Willall racing do the build for me. Will keep the stock Akebono brakes, I think they should handle the increase in power. I am aiming for about 310-330 rwkw on Pump98, stock is about 190-200 rwkw. It is my only car and my DD currently. I am on the alcohol interlock system so I legally can only drive this car atm. Just wanted to get peoples opinion if they think I will pass a road worthy inspection and or emission testing after the full build is done. Cheers.

I do love my Z, next fanciest thing after the GTR lol Only reason why I didn't wait was because last year when i bought the Z, I just got my license back after a 3 yr disqualification lol so I couldn't wait any longer.

Lol Ok probably not for me. Just tempting koz cars are my life lol n ofcourse the GTR is a dream. Only reason why I was tempted was because I know people who go and get $30K loans on cars alone, so I was thinking of doing it to get a GTR. I bought my new Z last year outrite. So GTR maybe later when I am making more money. For now I will keep the Z and TT.

Should I buy a GTR? GTR is basically my dream car. But need ask a few questions here to see if it is for me. I know you would have to be a welathy person to own and drive a GTR. But I would like to know what are the running costs for a GTR, like servicing and insurance, would it be for me? I only have an income of $50K a year, but it is basically all disposable to me, koz I live with parents. I currently own a 370Z MY15, and was planning on spending $20-30K upgrading it to TT with hopefully around 450-500whp. But then I thought, since there are used GTRs going for under $100K, I could sell my Z, for around $40K, save upto $30K (by April) and borrow $30K from the banks to buy a used GTR. But obviously I would need to know if this will work for me, the GTR will be my daily, and maybe track it a few times a year. If I break something in it, would I be looking at massive costs? I love my Z but should I upgrade to the bigger brother, or just put some steroids into my Z and keep it? Thanks for any help people.
